OK, Made custom textures in Photo Shop and converted them to a .wad file in Wally. No texture is larger than 256 X 256. .wad file installed in czero folder of server. .bsp file installed in Maps folder. Sprites in Sprite folder, Models in model folder sounds in sound folder. All are installed the same way (same paths) that I have them on my machine.
The game doesn't say anything when it crashes the server. If I am in Dust2 and change to the custom map with amx cmd. the server freezes at the point I was at in d2. I then have to restart the server.
Today purchased my own server so I can crash mine all day without anyone else being inconvenienced. Same results.
Map created in Hammer 3.4 compiled with batch compiler. It isn't my first map but it is my first using my own textures.
